GEZE Slimchain for a Range of Window Types

The GEZE Slimchain actuator operates at 24V DC, making it ideal for use in buildings that require low voltage for user safety, such as schools, healthcare facilities, offices, and other public spaces. The Slimchain is suitable for:

• Top, side, and bottom hung windows
• Parallel opening and projected top hung designs
• Timber, aluminium, or PVC window

With a 300mm stroke length, the Slimchain delivers reliable window operation. The drive is DIN right handed and each kit includes brackets (Set A or Set B, depending on window opening direction) for a complete installation.

Manual Window Open/Close Control for User Comfort and Ventilation

The included LTA 24 ZA switch gives building users direct control over window opening and closing, which is particularly useful in spaces where window access is limited. It's a simple way to support natural ventilation and regulate temperature without complex automation.

The GEZE DMS 5 control module and power supply provide reliable operation. Both units are DIN rail mounted and can be housed inside the included GEZE surface enclosure, helping keep the installation neat and protected.

Build Your Own Window Control System With GEZE 

This window actuator kit is designed for manual operation in natural ventilation systems. It’s ideal for retrofits, refurbishments or new installations where straightforward, low voltage control is needed for a single window.
